PORTABLE DOG.

Application filed June 11,

To all whom it may conccwt:

Be it known that I, di'isnrri ll. i'l'i' cmin, a citizen of the United States, residing at Stamford, in the county of Fair-held and State of Connecticut, have invented certain new and useful ln'iprovements in Portable Dogs, of which the following a specification, reference being bad to the accoi'npanying drawings.

This invention relates to devices of that character which are used for holding doors closed, Window sashes from being opened, and used by carpenters for the purpose of holding; one timber abutted against another.

The general object of my invention is to n'ovide a device of this character which is of very simple, cheap construction, and which may be used. for a large variety oi purposes, and which when in use will hold two parts from shifting relative to each other.

A further object is to provide a device of this character which is made from one piece oil: metal and which is very strong and thoroughly effective for the purposes stated.

My invention is illustrated in the accompanying drawings, wherein I Figure 1 is a top plan view ott my improved holding dog;

Figure 2 is a side elevation of the same;

Figure 3 is a fragmentary view of a window sl'lowing my holding dog; applied thereto Figure 4; is a fragmentary view illustrating the manner in which the holding dog); is applied to hold a door from movement;

Figure 5 is a fragmentary vertical section of window sashes showinghow my dog; is applied thereto.

Referring to these drawings, it will be seen that my improved dog; is made from a fiat strip of mild steel about thick, ll long and 12,-" wide, this strip 10 at one end being" slightly curved downward, as at 11, beveled upon its upper surface, as at 12, and provided with teeth 13. The opposite end of the strip is left of its full thickness but serrated to provide teeth 14- which extend entirely across the end edge of the strip. The blank from which this (1053 is made is formed with two slots '1 5 extendin r inward and toward the teeth 1.4:, these slots 1921. Serial No. 476,877.

terminating approximately an inch from the teeth lei and the metal exterior to the slots is bent downward to form prongs 16, these prongs gradually tapering toward their lower ends and sharpened to a point It will be seen that with this construction the prongs 16 may be forced into the floor, plank or timber and that it then force be applied against the serrated edge 14, the teeth 13 will bite into the wood or other material against which the teeth are placed, the prongs 16 acting as a fulcrum tor the dog.

This dog can be used as a door fastener or door jam by placing the short end of the dog against the door, the teeth 14 confronting the door, and the prongs 16 rest upon the floor or forced slightly into the floor. Then if anyone attempts to open the door, the force exerted against the dog will cause the teeth 18 to be forced into the floor and the dog will hold and prevent the door from being opened. It maybe also used as a sash fastening device. By placing the doe; upside down on top of the lower sash, the teeth lei against the lower sash, and the teeth 13 against the upper sash, then if any effort be made to open the lower sash, the teeth 13 will be forced into the upper sash and vice versa. It may also be used by floor layers as a dog for holdinp; the planks oi the floor :in place while they are being nailed, The dog); can be placed anywhere on the floor and the end. of a board he abutted against the front teeth of the dog, which will thus hold the boards from any sliding or shitting movement, rendering it easy to fit the piece of flooring. It is adapted to a number of other uses, and indeed anywhere where it is desired to hold a member from moving relative to another member.

I claim z- 1. A dog of the character described com prising a body formed of a relatively thin strip of metal, one end of the body being slightly bent and beveled and formed with teeth, the opposite end of the body having teeth, and prongs projecting at right angles to the body and forming a fulcrum therefor, said prongs being disposed adjacent the last named set of teeth.

2. A dog of the character described having a body formed of thin metal the body having a pair of slits extending inward and toward one end of the body and formed to define laterally disposed prongs, said prongs being bent downward at approximately ri 'ht angles to the body and pointed, that end of the body adjacent said prongs being serrated, the opposite end ol' the body having its outer fave beveled and its under 'ince slightly curved downward l0 and the edge serrated.

In testimony whereof I hereunto uiiix my signature.

JOSEPH E. AUGLAIR.
